Hello,
is there a convenient way to suppress only *specific* warnings? (I know about
?suppressWarnings)
I depend on another package, from which I want to suppress only some warnings,
but not others.
This is difficult in most cases, because most packages don't give enough
information to distinguish among their warnings. You could probably do
it based on the message as follows, but the test won't work if someone
is running in a locale where the warning message has been translated to
a different language:
x <- 1:10
x + 1:3 # gives the warning:
In x + 1:3 :
longer object length is not a multiple of shorter object length
To suppress just this one, try this:
withCallingHandlers(x + 1:3,
warning=function(w) {
if (grepl("longer object length", w$message))
invokeRestart("muffleWarning")
} )
